Upgrade dependencies especially zimscraperlib 3.x

[benoit74]

The primary goal of this PR was to upgrade to zimscraperlib 3.x to benefit from VideoLowWebm preset v2.

However, while working on it, it became clear that other things had to be fixed / where low hanging fruits.

This PR will probably induce a v3 of the scraper, the fact that we now check metadata by default is clearly a breaking change.

Make some progress on #145
Fix #169
Fix #152
Fix #148

Changes

• Upgrade dependencies and migrate to hatch-openzim
• Add basic support for disabling metadata check if needed
  • We could imagine more advanced behavior where we disable only the settings which make sense according to user input
• Add support for long description for ted2zim
  • long description is not available for ted2zim-multi because description is already not available anyway, they are always automatically computed
• Display FFMPEG logs in case of failure
• Cleanup incomplete/failed video download file
• Add support for long description
• Validate ZIM metadata as early as possible
• Fix ZIM language metadata
  • it is now a list instead of a single value
  • we ony fallback to "eng" when "we don't know the language", not when there are many languages
  • when there are many languages, the CSV list is not yet ordered properly, we only have a hack to put "eng" first if present, since it is the most present language for sure in 99% of the cases (see for issue removing the hack)
• Fix computation of automatic description and long description (through zimscraperlib automated truncations)
